COATED METAL BUTTON OR SIMILAR ARTICLE AND METHOD OF MAKING SAME.

To all whom it may concern:

Be it known that I, JAMES F. QUINN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Coated Metal Buttons or Similar Articles and Methods of Making Same, of which the following is a specification. L

My invention relates to the production of a coated metal button, which shall resemble a pearl button but which will be much more cheaply made, and comprises both the button, or other similar metal article and the method of producing the same.

Throughout the specification, the term button is intended to include other similar articles, whether made in the shape of a button or other similar device.

In practising my invention I dip the-button blanks, which are preferably made of brass, or similar metal, more electro-positive than silver, into a so-called silver solution, which comprises for example, 2 parts of silver chlorid, 6 parts of potassium carbonate, 2 parts of whiting and-3 parts of sodium chlorid, together with a" suflicient amount of water, to form a thin liquid. In.

place of this particular silver solution, any other solution which will electro-plate silver upon the metal button may be used. The metal button after being allowed to remain in the bath for a short time, say 10 or 20 minutes, is removed from the bath and dried. The button, coated with silver, may then be dipped, if desired into a transparent or semitransparent cement. Such cement may if desired be prepared by rubbing together in a mortar, 2 parts of calcium nitrate, 25 partsof water and 20 parts of powdered gum arabic. The button is then dried. In place of this particular cement a mixture of 75 parts of unvulcanized rubber, 60 parts of chloroform and 15 parts of gum mastic or mastic varnish may be used. The silver plated button, with or without the cement coating, is next treated with a coating material comprising a so-called pearl mixture, which may be composed of '1 part of Baroque pearl powder, and 2 parts of Japanese thick lacquer. By reason of the transparency of Specification of Letters Patent.

Application filed January 16, 1915. Serial No. 2,736.

the cement, if the same is employed, and by reason of the partial transparency of the.

coating of pearl mixture, the appearance of the finished article is materially different than would be the case if the pearl mixture wereapplied directly to the surface. of the brass. The button is then removed from the bath, and after drying, is ready for packing and shipping. Any mechanical treatment,

such as boring the holes, or applying the sitions of the silver solution cement and the pearl mixture, I do not desire to be limited to the particular compositions described, but

may substitute other silver solution, or other I cement, or other pearl mixture.

What I claim is 1; A metal article comprising a metal more electro-positive than silver, a closely adherent coating of silver upon said article, and a .second coating of powdered pearl and lacquer thereupon.

2. A brass article having a coating of silver, and a second coating thereupon, said second coating comprising an intimate mixture of pearl powder and lacquer.

3, A method of coating metal articles, comprising a metal more electro-positive than silver, said process comprising dipping the said metal article into a solution capable of plating silver thereupon, and thereafter coating the silver plated article with a mixture containing powdered pearl and lacquer.

4. A brass article having a coating of silver and a coating of pearl andlacquer, said two coatings being bonded together, by means of a cement.

5. An article having a silver surface and a coating thereupon, said coating comprising an intimate mixture of pearl powder and lacquer.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES F. QUINN.
